GEORGE WILLIAM JACKSON AND ELI OSCAR FEARNLEY, OF MANCHESTER, ENGLAND.

MUL'TICOLOR-PRINTING MACHINE.

SPECIFICATION forming part Of Letters Patent NO. 697,487, dated April 15, 1902.

Application filed June 15, 1900. Serial No. 20,427. (No model.)

T all whom it may concern:

Be it known that we, GEORGE WTLLIAM JACKSON, residing at'St. Anns street, Brad ford, Manchester, and ELI OscAR FEARNLEY, residing at Oresswell Terrace, Miles `Platting, Manchester, in the county of Lancaster, England, subjects of the Queen of Great Britain, have invented new and useful Improvements in Multicolor-Printing Machines, of which the following is a specification.

Our invention relates to new and useful improvements in multicolor-printing machines,

and is particularlyapplicable to certain types of machines which are known as lithographic, Warfedale, or flat-bed machines and platen machines.

The object of our invention is to enable any kind of letter-press work or any kind of pictorial work to be produced in any number of colors at one impression from one form of any size on the type-bed of a printing-machine.

In the accompanying drawings, Figure 1 is a side view of such portion of a {iat-bed machine as is necessary to show the application of our invention. Fig.. 2 is a plan on line A A, and Figs. 3 to 9 are details of the same. Fig. 10 is a side View of a platen-machine with our invention applied, and Fig. 11 isa plan of portion of the same. Fig. 12 is a transverse section, Fig. 13 a back view, and Fig. 14 a plan of ink-duct.

In the views similar letters refer to similar parts.

In applying our invention to lithographie or flat-bed machines we support between cheeks, as a, ink-ducts, as c c c2, ink-cylinders, as d d d2, and ductor-rollers, as e c e2, grouped so as to form separate sets, each set, which comprises an ink-duct, an ink-cylinder, and a ductor-roller, being superposed in positions collectively and relatively with distributingrollers, as ff' f2, that are supported between cheeks, as b, each of said distributing-rollers having contact with all or certain portions of rings or pattern -`blocks provided `with a designplaced on shafts, as g g g2, that are supported between the cheeks b, said rings or pattern-blocks being arranged so that any or all of them may be placed in contact with a form-inking roll, as j. The ink is supplied from the ink-ducts c c' c2. Each of said inkducts may be divided into any number of compartments for diiferent colors by partitions, as 7o, which we secure in the required positions by forming the outer end of each partition with a slotted projection 7o', as shown in'Figs. 13 and 14, through which the screwed end of a T'headed bolt k2, retained in position in a slot 7c3 in the ink-duct and projecting therefrom, is passed and fastened by a nut h5. The ductor-rollers rest on the distributing-rollers and are caused to oscillate by the contact of the cams m2 with the runners p that are placed on the shafts passing through the ductor-rollers, the ends of said shafts being retained loosely in bearings, as Z l Z2, that are formed at the ends of brackets, which are placed loosely on the shafts carrying the inkcylinders.

The segment-rings r (shown in Figs. 3, 4, 5, and 6) are placed on transverse shafts g g' g2, extending between the side cheeks b in such positions that the peripheries of said rings shall have contact with the periphery of the form-inking roll j and are caused to rotate at equal speed by toothed wheels w, placed on the shafts carrying the rings gearing into each other, each of said wheels also gearing into a toothed Wheel placed on the shaft carrying the form-inking roll, which is revolved by the rack q, that is iitted at the side of the table of the machine. The segment-rings of one series are formed to receive the ink from the distributing roller and deliver it to dierent parts of the form-inkin g roll, the intervening spaces on the form-inking roll receiving ink in like manner from the segment-rings of another series. Fig. 3 is a view of one side ofa segment-ring'. Fig. 4 is a transverse section, and Fig. 5 a v iew of the reverse side of said ring. Fig. 6 is a modication of the same. We form the main portionr of the ring with semicircular slots r' therein, through which to pass studs, as r2, by which to retain segments of rings, as s, in any required position after circumferential adjustment, either as shown on the drawings or with greater or less spaces between them. A segment, as s', may form a part of the main ring. The projections r3 are for the purpose of setting the segments of rings at the correct radius, but other equivalents, such as shown in Fig. G, may be em- IOO ployed for securing segments, as s, in the main ring r. These rings are placed on the shaft in the order and necessary positions for imparting the required color of ink to portions of the primary cylinder, leaving blanks thereon that are supplied with ink of another color by means of like rings in another series. After the required longitudinal and rotary adjustment the rings are retained in their positions on the shaft by a split nut, as m, which when screwed up into the angular portion m clips the shaft. For the purpose of distributing the ink evenly on the surface of the forminking roll j for straight-line running we employ (in place of a laterally-moving distributing-roll) a waved ring p, as shown in Figs. 7, S, and 9, which are respectively a crosssection, face view, and edge view. The periphery of the waved metal rim may be covered with suitable elastic material p'. These waved distributing-rings p may be employed in combination with the segment-rings, but in any case should he free to turn independently of the form-inking roll, as by mounting thedistributing-rings@ loose upon their shafts or otherwise. These free waved rings without lateral motion distribute the ink better and with less injury to the inking-roll than ordinary distributing-rings can do. Circular pattern-blocks provided with a design may in like manner be employed for pictorial work by placing the pattern-blocks on the shafts g, g', and g2 in place of the aforesaid segmentrings.

In working our invention the frames a and b, with the form-inking roll and the several rings and rollers hereinbefore described, are moved along the table until the periphery of the form-inking roll is within about a quarter of an inch of the periphery of the impressioncylinderj?. The form passing under the forminking roll receives therefrom always in identical positions on the different parts of the form the diiferent colored inks, which are then transferred to the impression-cylinder in the usual manner.

When our invention is applied to platenmachines, as shown in Fig. 10, the ductorrollers e e e2 may transfer their colors direct to the rings or stereos on the shafts g g g2 and the ink transferred from the roll j to an inking-roller fu,which inks the form, and the impression is taken on the platen u in the ordinary manner.

IVe claim as our inventionl. In a multicolor-printing machine, the combination of an inking-cylinder as j, with adjacent shafts carrying rings as r, adjustable on the shafts and segments ass, circumferentially adjustable on the rings, substantially as described.

2. In a multicolor-printing machine, the

'combination of an inking-cylinder as j with superposed shafts as g, g g2, grouped around said roll, the said shafts carrying rings as r, adjustable on the shafts with segments as s circumferentially adjustable on the rings, substantially as described.

3. In a multicolor-printing machine, the combination of an impression-cylinder, form and a form-inking roll as j, with adjacent shafts carrying rings as r adjustable on the shafts with segments as s, circumferentially adjustable on the rings, substantially as described.

4. In a multicolor-printing machine, the combination of an impression-cylinder, form and a form-inking roll as j, with superposed shafts g g g2 grouped around said roll, the said shafts carrying rings as r adjustable on the shafts withsegments as s circumferentially adjustable on the rings, substantially as described.

5. In a multicolor-printing machine, the combination of a form-inking roll asj with shafts as g, g, g2, grouped around said roll, the said shafts carrying rings as r adjustable on said shafts with segments as s circumferentially adj ustable on the rings, an ink-duct, ductor roller and distributing-roller being combined with each ring-shaft, all substantially as described.

G. In a multicolor-printing machine, the combination of a form-inking roll with waved ink-distributing rings free to turn independently of said roll to distribute lines of ink evenly thereon, substantially as described.

7. In a multicolor-printing machine, the combination of a form-inking roll as j with waved ink-distributing rings p to distribute lines of ink evenly on the printing-cylinder and shafts having rings as r adjustable on the shafts and segments as s circumferentially adjustable on the rings, substantially as described.

8. In a multicolor-printing machine, the combination of an impression-cylinder,form and form-inking roll with waved rings asp free to turn independently of said inking-roll, and circular pattern-blocks provided with a design, arranged around said inking-roll and geared to revolve at equal speeds, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
